 This project contains an example of Lambda function using the CloudFormation module of Powertools for AWS Lambda in Java. For more information on this module, please refer to the [documentation](https://awslabs.github.io/aws-lambda-powertools-java/utilities/custom_resources/).
 
+In this example you pass in a bucket name as a parameter and upon CloudFormation events a call is made to a lambda.  That lambda attempts to create the bucket on CREATE events, create a new bucket if the name changes with an UPDATE event and delete the bucket upon DELETE events.   
+
 ## Deploy the sample application
 
 This sample can be used either with the Serverless Application Model (SAM) or with CDK.
 
 ### Deploy with SAM CLI
 To deploy it using the SAM CLI, check out the instructions for getting started in [the examples directory](../README.md)
+Run the following in your shell: 
+
+```bash
+cd infra/sam
+sam build
+sam deploy --guided --parameter-overrides BucketNameParam=my-unique-bucket-20230718
+```
 
 ### Deploy with CDK
 To use CDK you need the following tools.
 
 * CDK - [Install CDK](https://docs.aws.amazon.com/cdk/v2/guide/getting_started.html)
-* Java 8 - [Install Java 8](https://docs.aws.amazon.com/corretto/latest/corretto-8-ug/downloads-list.html)
+* Java 11 - [Install Java 11](https://docs.aws.amazon.com/corretto/latest/corretto-11-ug/downloads-list.html)
 * Maven - [Install Maven](https://maven.apache.org/install.html)
 * Docker - [Install Docker community edition](https://hub.docker.com/search/?type=edition&offering=community)
